Abstract

There is provided a cationic organic peroxyacid having the general formula wherein: R1 is an optionally substituted, linear or branched, C8-C12 alkyl or alkenyl group; R2 and R3 are each a methyl group; R4 is an optionally substituted, linear or branched C3-C5 alkyl or alkenyl group; p is 0 or 1; z is an integer selected from 0-3; y is an integer selected from 0-5; w is 0 or 1; and X- is a counter anion. This peroxyacid was found to have good bleaching performance without showing incompatibility with anionic surfactants.

Claims

exact text as granted — not AI-modified
We claim: 
     
       1. Cationic organic peroxyacid having the general formula ##STR8## wherein: R 1  is an optionally substituted, linear or branched, C 8  alkyl or alkenyl group, R 2  and R 3  are each a methyl group;   R 4  is an optionally substituted, linear or branched C 5  alkyl or alkenyl group;   p is 0 or 1; z is an integer selected from 0-3;   y is an integer selected from 0-5; w is 0 or 1; and   X -   is a counter anion.   
     
     
       2. Peroxyacid according to claim 1, wherein p, z, y, and w are all 0. 
     
     
       3. Peroxyacid according to claim 1, wherein R 1  is an unsubstituted linear C 8  alkyl group. 
     
     
       4. Peroxyacid according to claim 1, wherein R 4  is an unsubstituted, linear C 5  alkyl group. 
     
     
       5. Peroxyacid according to claim 1, wherein X -   is selected from the group consisting of NO 3   - , HSO 4   - , SO 4   2- , CH 3  SO 4   - , and R 5  (O) p  SO 3 , wherein R 5  is a C 2  -C 20  substituted or unsubstituted radical selected from the group consisting of alkyl, alkenyl, and aryl group, and p is 0 or 1. 
     
     
       6. Peroxyacid according to claim 5, wherein X -   is selected from sodium dodecyl sulphate (SDS), sodium fatty acid alpha sulphonate (SFAS) and tosylate. 
     
     
       7. Bleaching detergent composition, comprising from 3 to 40% by weight of one or more surface-active compounds, from 5 to 80% by weight of one or more detergency builders and an effective amount of a cationic peroxyacid according to claim 1, as the bleach component. 
     
     
       8. Composition according to claim 5, wherein the cationic peroxyacid is present at a concentration of from 0.5 to 15% by weight. 
     
     
       9. Bleaching additive composition, comprising from 50 to 90% by weight of a cationic peroxyacid according to claim 1, as the bleach component.
